Condition before being touched

Hi i bought my first atv last week, mostly for plowing. its a 94 yamaha big bear 350 4x4, with plow, new front axles, carb rebuild and some other stuff for $900. in todays prices, i think it was a pretty good deal. I plan on tearing it down and doing a semi restoration in the summer. its been clearly neglected so i suspect i will need to do a fair amount.
couple questions. 
1. parts and manuals, so far i know it needs front shocks, tie rods, brakes, cables, lots of small stuff, whats your guys favorite online atv parts store? where can i find a good repair manual?
2 - starts and drives great, shifts a bit hard? not sure whats normal because i dont have a point of referance. i have to almost lean back in the seat and lever my foot up to get it to shift, seems like there is either alot of play in something (shift lever itself is tight) or there is a long travel, or it just dosent want to shift. also the hi / low / reverse lever needs to go past the gate a bit to actually shift into gear, and seems to need me to shift into nutral before shifting into reverse (not sure what your supposed to do). also wondering a bit about the history of the machine, because the plastics have a slot for a dash mounted shifter, but the one on it is a gated shifter right above the pull starter. 
3. seat and plastics repair, seat is quite torn up with a seat cover over it, plastics are pretty cracked up, these items i havent found replacements for for any reasonable price, i dont care a whole lot about asthetics but whats the best way to functionally repair these things? is there reasonably priced replacements somewhere? i plan to bedline the whole thing after im done. 
4. there was no title, but i did get a bill of sale, will it be difficult to get it titled / registered? (im in mn)
thanks in advance for your help, looking forward to being part of the community

Hello Folks....new to the forum.  I have two Warriors (87 and 92), and an 89 Big Bear.  Looking for some help with engine issues on the warrior, and my 89 Big bear backfired and died. Got spark, got gas, seems to have compression, (but haven't tested it yet...next). She rolls over good, maybe too good...seems soft. Have spark and enough compression to blow gas mist out the plug hole when cranking. Suggestions, Been running great since we got it.
